eSource is a collection of online chapters that provide an introduction to selected behavioral and social science research approaches, including theory development and testing, survey methods, measurement, and study design.  eSource was developed for OBSSR around 2010 by the New England Research Institute (NERI) with contributions from topic experts.  These chapters have not been updated to reflect advances in the past decade, and the exercises are not interactive in PDF format, but OBSSR continues to make these chapters available online for those who wish to use them as supplementary teaching materials.
